Abstract
A new sol-gel process using inorganic salts instead of metal alkoxides has been successfully developed for preparing Ba(Mg1/3Ta2/3)O3. Pure Ba(Mg1/3Ta2/3)O3 polycrystalline powders were obtained by calcining the derived precursors at 1100°C. The particle size of the obtained fine particles was around 0.1 μm. The ordering parameter of the sintered Ba(Mg1/3Ta2/3)O3 was found to strongly depend on the calcination temperatures. Sintering the 1200°C-calcined powders at 1690°C resulted in the ordering parameter to be 0.82, which is greater than that obtained in the conventional solid-state reaction. The improvement in the ordering parameter is attributed to the enhanced compositional homogeneity in the powders prepared via the sol-gel process.
